March Scopes Owner, Claudio Flores (Chile) has shared his review on 4-40×52 Genesis on Youtube videos.

Make sure the 4K HD setting is selected on the you tube app or channel.

4-40×52 Genesis has 86MIL, 296MOA elevation travel amount without utilizing any external accessories and is capable of engaging targets from 20 meters up to 3 miles (4827m). The unique design of Genesis scopes (the scope itself inclines) allow the shooter to always see through the central part of the lens producing clarity, definition, and minimal chromatic aberration even when at extreme elevation. You can achieve a perfect IQ throughout all the magnification range and elevation travel.
